Is there a Windows version?

I can only see a Unix version...

Actually there's only a Windows version. The game's main executable is an .exe, and must be run on Windows or using some kind of emulator (like Wine).
I'm preparing a guide for Mac and Linux users exactly for this purpose.

If you have trouble as a Windows user though, check THIS TOPIC.

Thanks for getting in touch!
